Kolkata Police chief among 'best in world': Mamata Banerjee

West Bengal CM Mamata Banerjee on Sunday said the Kolkata Police Commissioner Rajeev Kumar, wanted for questioning by the CBI, is among the "best in the world". She added, "He is working 24x7, and was on leave for only one day recently." The BJP is misusing power to take control of the police and destroy all institutions, she said.
